Mother of footy star's son reveals NRL 'group sex culture'

X-rated stripper Belinda Medlyn is at the centre of a modern-day "courtship" which started on Instagram three years ago and culminated in five secret sex sessions - including on the eve of Warriors star Bodene Thompson's match day.

She consented to group sex with the $260,000-a-year rugby league star, including a foursome with two other NRL players.

Ms Medlyn and Thompson - at the time a Warriors player - had a secret romp hours before his team took on the Bulldogs and lost at ANZ Stadium on September 6, 2015.

The Daily Telegraph can reveal Thompson's 15-month-old boy Hendrix was conceived that night as a teammate looked on.

The secret relationship was conducted behind coaches' backs and in team hotel rooms. In a series of online messages, the pair even sent pictures of friends and NRL players to each other for consideration for group sex.
